Multicellular Quadruple Colorectal Cancer Spheroids as an In Vitro Tool for Antiangiogenic Potential Evaluation of Nanoparticles

چکیده
The encapsulation of bevacizumab (BVZ), angiogenesis inhibitor antibody, into nanocarriers is explored aiming at enhancing its efficacy in colorectal cancer (CRC) treatment while eliminating potential side effects. Still, the translation such nanomedicines clinics not straightforward owing to their preclinical screening simplistic models, that do mimic complexity and heterogeneity CRC microenvironment. Herein, development a multicellular spheroid as an advanced model capable antiangiogenic novel proposed. For that, quadruple co-culture established through combination HCT116 cells, human pulmonary microvascular endothelial cell (HPMEC), fibroblasts, macrophages. It demonstrated developed displays intrinsic features, organization expression tumor microenvironment, extracellular matrix, formation necrotic core. Moreover, shown be composed mostly (93%), followed by hypoxia-inducible factor (3%), HPMEC macrophages (1%). Gellan gum/chitosan nanoparticles encapsulating BVZ exhibit superior properties when compared free BVZ. Overall, can further promising approach treatment.

Preparation, in-vitro characterization and pharmacokinetic evaluation of Brij decorated doxorubicin liposomes as a potential nanocarrier for cancer therapy
The aim of current study was to investigate the effect of Brij decoration of liposomes on in vitro and in vivo characteristics of the nanocarriers. Two hydrophilic Brij surfactants (Brij 35 and Brij 78) with almost similar molecular weight but differing in acyl chain were incorporated into liposomal bilayers at two percentages (5% and 10%). Conventional liposomes (CL) containing egg phosphatidy...

Abstract Background : Cancer has not been elucidated in colerectal site. C-reactive protein (CRP) is a product synthesized in hepatocytes and has been reported to be up-regulated by such proinflammatory cytokines as interleukin-1 (IL-1), interleukin-6 (IL-6), and tumor necrosis factor (TNF). The significance of a preoperative serum elevation was evaluated using CRP as a predictive i...
